Will I don't do very much of this and prob won't after this but this might go on for a few months but just can't drop 5 g on a unit to weld these things worst comes to worst I will have to keep tigin it but its taking to long I was thinking a millermattic 200 with a spool gun but not sure if that would work or not

The MM200 with a 30A would be a good inexpensive short term solution..

I am helping out a friends shop weld good size aluminum boxes and am welding with my dynasty 350 right now but it's way way way to slow and owner said they were wire welding them with spool gun or push pull set up Most the plate aluminum is 3/8 to 7/16 and they have been tacking on 1 in blocks to all four corners on these parts So my question is what set up would work for me ? I don't wanna spend the farm but would like to get a wire set up for this any advise would be great thanks in advance

Look at cyberweld or your local welding supplier. You can find the machine for about $2300.00

The MM252 is a decent machine... it has output and duty cycle nearly identical to the MM200...60% Duty cycle @ 200 amps.. will drive a 30A spoolmatic and it does have gun on demand which is convenient..

I have had both. The 350P and now the 252. I like the 4 roll drive on the 350P, but for the price, the 252 is a good machine. And as you stated, the 15A or 30A is an option and the gun I prefer over all the others.

Just to clarify don't mix up the older MM200 & the new multimatic 200, which can also be called a MM200. Two completely different units.

I run a MM250 with a 30a spool gun on the heavier aluminum I do. It works fine. I'm in a situation like you where I don't use it much but when I do it gets used for a day or two all day. This set up, a MM200/250/251/252 with a 30a is what I would recommend. If you buy it used you can always recoup your cost when done by reselling it.

Not knocking the 350p but if it's going to sit for long periods in the corner it doesn't make good business sense.

If you are going to run a spool gun.. you might as well bite the bullet and get either the 15A or 30A .... they weld well and are built to last and be used....
some of the others not so much... they are just trouble..

Lincoln MP350, with a Miller 30A spoolgun. One stop shop with Tig, Mig, Pulsed Mig, and Stick. always upgradeable software wise. Or for half the money a Lincoln MP300, which is the same as a MP350 with a simple software upgrade.

If your not really looking for a mig id say continue on tiging. If u really wanted a good setup for a mig and aluminum. My suggestion is the lincoln c300 with a push pull gun. That machine is sweet. Pry get knocked for saying that on here but its my opinion. Its what id buy for a mig. Only miller migs i ever really thought were really good are the xmt with a 70 series feeder.

Would a spoolmate 15 or 30 do it running off a old millermattic 200 thanks ?

Yes, it can do it but not very well. It has no run-in control which really is the key to starting the weld on alum. The 350P,350P-alum, and the 252 has run-in control. Tell your boss if he wants you to go faster buy a mig with the ability to burn alum and has run-in control.

The ThermalArc 252i Fabricator has run-in control, and you can buy a spoolgun for it.
